6-24V 3A Car USB Charger Module DC Buck Step Down Converter Power Supply Module
Product Description:
The new United States imported chips, definitely not homemade chips, disassemble chip.
The maximum output current of 3A, the long-running 2.1A, sufficient margin.
The new design, circuit design does not require electrolytic capacitors and tantalum capacitors (electrolytic capacitor life is short, there is a risk of explosion tantalum capacitors). Now with the use of high-end large-size solid ceramic capacitor circuit (MCC) 3
Very low ripple, 12V switch 5V 3A only about 10 mV ripple many peers have reached 500 mV or greater, the device will cause an invisible injury, severe can cause fault or damage.
The new program uses synchronous rectification circuit conversion efficiency is very high, in turn 5V 0.7A 6.5V when efficiency up to 97.5%, 12V turn 5V 1A when it reached 94%, unlike some peers only 60-70% efficiency . (Efficiency test removed the input reverse polarity protection diode and fuse drop).
Using flat copper inductors, maximize conversion efficiency. Reduce heat.
